RMP40 radio transmission probe

For workpiece inspection and job set-up on machining centres and multi-tasking machines.

Flexible probing solution.

Superior communication capability.

Outstanding performance for less scrap and higher profits.

Operating within the globally recognised 2.4 GHz ISM band, the RMP40 is suited for operation on machines of all sizes.

The robust transmission protocol and small body make the RMP40 the ideal choice for multi-tasking applications where the line-of-sight between probe and interface cannot always be maintained.
